>You've made this claim (thought without specifying why it's superior to the existing methods), and yet ignored the simple fact that a TIR post is just as bad, if not worse, then the post it replies to. At the very least, the post it replies to is at least, usually, on topic (Topicality is, of course, not the sole contributing factor to whether a comment is worthwhile).
I'm not ignoring that fact - it's just that I haven't accepted it. I agree that TIR posts do not derive value from adding valuable on-topic content. But I've suggested a way for them to derive value from another source. Given that, I don't accept the claim that they are just as bad as the posts they reply to. I thought (and still do) that the argument you were offering takes that as a premise. That's the point I made in the last comment, and I took it to be sufficient to show why your argument doesn't go through. I'm very much happy to be corrected if that's not the argument you had in mind.
The point about using existing tools/protocols is a different argument, and I think a good one. However, it doesn't bear on whether TIR posts are in themselves valuable or not - it only bears on the comparative value they have. Evaluation of that argument would require more knowledge than I have of the efficacy of different ways online communities enforce norms. Re the other points - I think there are interesting things to say about them, but I suspect that would take us off the central disagreement. I am however familiar with the other points about comment policy and downvotes etc... - I've used HN far longer than I've had this account. Whilst we're on issues of civility, I would say that suggesting comments come off as trolling, claiming people 'don't grasp' (which can mean 'don't understand'), and judging them on two sentence profiles don’t seem to me very useful. I was slightly brusque in claiming your comment was 'beside the point' - but did so to echo your comment.
I think I should point out that I don't commit to the claim that TIR posts actually are valuable - I just think it's plausible that they are.
